To gzllwhom; zit-may concern 7 Beit known that I, WILLIAMJG; Pnons'r,

a citizen ofthe. United 'States', residingeat Louisville, in-fthe county, of Jefl'erson and State of Kentucky, have inventedcertainnew and useful Improvements in vElectric EnamelingTools, and I-do hereby declare the followingfto be a full, clear, and-exact; description 1 of theinvention, suchw as W111 enable others skilled in the art'to which it appertains to make and use the same.

The invention relates to enameling tools:

andfhas forfits fobject the provision of an for inspection, replacement or other required purpose. A I

Other objects and advantages will be ap parent andsuggest themselves as the nature of the (invention-is understood: 2

While the; drawings illustrate an embodithat in. adapting the-i same; to meet different' conditions and. requirements, various changes in the form, proportion and minor details of Tconstruction -may beresorted a to:

without departing: from the: nature of the invention." i 7 Referring to the accompanying drawings forming-a part of the=application,

Figure 1 is a side view of anelectric enameling tool embodying;the invention,

Figure 2 is a reverse view of the too1, showing the same on a larger scale and having the covering plate of the switch housing removed,

Figure 3 is a detail perspective view of a portion of the switch assembly, the parts being separated and disposed in a group,

Figure 4 is a central longitudinal section, the vibrating mechanism being in elevation,

Figure 5 is a transverse section on the line 55 of Figure 4, looking in the direction of the arrows and showing the parts on a larger scale,

Figure 6 is an enlarged end view of the tool, and

Figure 7 is a detail perspective view of the core, the parts being separated.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tool comprises a frame or hollow casing including a head 1, a handle 2 and an intermediate neck 3 or housing. for" the switch: mechanism; These parts preferably,

are of integral formation and consist of light casting .Hof aluminum or other metal An electric vibrating mechanism i, of any approved construction and make, is disposed within the :headportion 1 of the casing and is adapted to be operated by an electric current derived from any suitable source by means'of an electric cord. 5 or other'well' known form of conductor adapted tobecoupled to: a-s0cket or other outletin a manner well understood.

A core of-insulating: material iseenclosed within the handle 2 and comprises; a -main section 6 and a complemental section 7 thetwo sections when assembled beingsecured by} suitable fastening means'in anypreferred' way: Two contacts8 and 9am carried by the core and are-preferably attachedto the main-section- 6; The contact -9hasone terminal of the'heliX of the electric vibrator ment ofithe invention, it is to be understood 4 connected thereto and awire or-conductor lO hasithe 'other' terminal of the helix connect'ed thereto. A wire orconduct'or ll'is connectedto'the contact 8 and both 'wires or c'onductorslO- and =11 terminate in c0upling ends :12 which admit of' the wires of theelectric cord-5 being-.coupled thereto; A

which is clamped between the end of the nut 14 and the end of the handle 2. The wires of the electric cord 5 terminate in coupling ends which are carried by the plug 13 and are adapted to engage the coupling ends 12 whereby the connection is completed when the parts are properly assembled, as indicated most clearly in Figure 4.

The switch includes a circuit closing member 16 which consists of a plate or strip of metal of a length to engage both ofthe contacts 8 and 9. The part 16 is clamped between two elements 17 and 18 of insulating material and mounted upon a stem 19 which has a threaded portion 20 upon which the parts 16, 17 and 18 are mounted and made secure by a clamp nut 21. The stem 19 has a reduced end portion 22 which receives an expansible helical spring 23 which is confined between the nut 21 and a hollow nut 24 threaded into an edge portion of the part 3 of the frame or casing. The tension of the spring 23 may be regulated by adjustingthe hollow nut 2 The stem 19 extends through the opposite edge portion of the part 3 and is adapted to be engaged by means of a lever pivoted at 26 and disposed in a recess 2'7 formed in the outer side of the part 3. The projecting end portion of the lever 25 extends along a side of the handle 2 and is spaced therefrom to be operated by pressure of the hand for closing the circuit when the tool is in operation for supplying the material to the surface to be enameled.

The outer or front end 01 the frame or casing 1 is closed by means of a plate 28 which is bolted or otherwise secured thereto. This plate 28 carries the electric vibrating mechanism 4. A threaded collar 29 is attached to the plate 28 and the sieve (not shown) or other part carrying the enameling material to be distributed is adapted to be coupled to the tool by means of the collar 29. The collar 29 is provided with a base 30 which is secured to the plate 28 by means of machine screws or other suitable fastening m'eans.

A side of the housing 3 is open, whereby access to the switch mechanism may be had with the greatest convenience. A plate 31 closes the open side of the housing 3 and is retained in place by machine screws or bolts 32. The core, carrying the contacts 8 and 9 and the wires 10 and 11, is insertable into the. handle 2 and removable therefrom through the outer end and is retained in place by means of a nut 14 and the stem 19, the latter passin transversely therethrough.

When the tool is in operation, it is grasped by means of the handle 2 and the switch operating lever 25 is adapted to be actuated either by tightening the grip or by applying pressure thereto by means of the thumb. In either event, inward movement'of the outer end of the lever 25 moves the stem 19 inward the vibrating action of the container ceases.

It will thus be understood that the service of the tool may be continuous or brief as required, according to the manipulation of the switch lever 25.

\Vhat is claimed is: V An enameling tool consisting of a onepiece cas ng,zsaid casing having a hollow tubular handle, a conductor-means securing 'nut externally threaded on one end of said handle, thecasing being increased in thickness at the other end of the handle to provide an outwardly disposed shoulder and to form a neck, said nut and shoulder providing abutments for the hand, said neck having an exterior longitudinally extending re 7 cess,"a switch carried by. said neck having an operating member disposed in said recess and extending rearwardly and having its gripping portion disposed intermediate said nut and shoulder so that it is engageableand operable by the same hand which grasps the handle, a hollow head integral with and of greater diameter than the neck extending from the neck, a vibrating mechanism in the head, the outer end of said head being open,

and a-sieve-mounting plate closing said end.

In testimony whereof I afiix my signature in presence of two witnesses.
